Development of ARCADIA: a tool for assessing the quality of peer-review reports in biomedical research.

Objective: To develop a tool to assess the quality of peer-review reports in biomedical research.

Methods: We conducted an online survey intended for biomedical editors and authors. The survey aimed to (1) determine if participants endorse the proposed definition of peer-review report quality; (2) identify the most important items to include in the final version of the tool and (3) identify any missing items. Participants rated on a 5-point scale whether an item should be included in the tool and they were also invited to comment on the importance and wording of each item. Principal component analysis was performed to examine items redundancy and a general inductive approach was used for qualitative data analysis.

Results: A total of 446 biomedical editors and authors participated in the survey. Participants were mainly male (65.9%), middle-aged (mean=50.3, SD=13) and with PhD degrees (56.4%). The majority of participants (84%) agreed on the definition of peer-review report quality we proposed. The 20 initial items included in the survey questionnaire were generally highly rated with a mean score ranging from 3.38 (SD=1.13) to 4.60 (SD=0.69) (scale 1-5). Participants suggested 13 items that were not included in the initial list of items. A steering committee composed of five members with different expertise discussed the selection of items to include in the final version of the tool. The final checklist includes 14 items encompassed in five domains (Importance of the study, Robustness of the study methods, Interpretation and discussion of the study results, Reporting and transparency of the manuscript, Characteristics of peer reviewer's comments).

Conclusion: Assessment of Review reports with a Checklist Available to eDItors and Authors tool could be used regularly by editors to evaluate the reviewers' work, and also as an outcome when evaluating interventions to improve the peer-review process.
